At first, as shown in Figure 5, under the situation of Ts＞Tr, when Ts is lower than 20 ℃, carry out warming temperature till Ts reaches.When Ts reaches, survey and be activated,, repeat to heat up when detecting when being lower than Ts-1 ℃.When Ts is higher than 20 ℃ but when being lower than 24 ℃, carry out warming temperature till Ts reaches.When Ts reaches, survey and be activated,, as shown in Figure 7, heat up and dehumidification operation is implemented to repeat intensification/dehumidifying and circulates when detecting when being lower than Ts-1 ℃.
In addition, when Ts is higher than 24 ℃, be based upon to being forced to property of Ts maximum 24 ℃, carry out warming temperature till Ts reaches.Survey when reaching 24 ℃ and be activated, when detecting when being lower than Ts-1 ℃, intensification/dehumidification operation is implemented, and as shown in Figure 7, heats up and the dehumidifying circulation repeating.After Ts reached, during intensification/dehumidification operation, room temperature was surveyed and is left in the basket, and same intensification/dehumidifying circulation is repeated, and withdraw from and heat up and dehumidification operation, and unique possible way is from external key input operation locking signal.
Next, when Ts＜Tr, as shown in Figure 6, when Ts was lower than 20 ℃, warming temperature did not carry out, and after Ts is reached, located to heat up and dehumidification operation at+1 ℃.When Ts is lower than 23 ℃, after Ts reaches, locate to heat up/dehumidification operation at+1 ℃, as shown in Figure 7.
When Ts surpasses 23 ℃ but when being lower than 27 ℃, when being reached, Ts surveys to start.More than Ts+1 ℃ locate dehumidification operation and be performed.When Ts surpasses 27 ℃, when Ts is reached, survey and start, more than Ts+1 ℃ locate dehumidification operation and be performed repeating and survey and dehumidifying.After Ts was reached, during heating up and dehumidifying, room temperature was surveyed and is left in the basket to repeat same intensification and dehumidifying circulation, withdraw from and heat up and dehumidification operation, and unique possible way is from external key input operation stop signal.
Next, under the situation of Ts=Tr, as shown in Figure 6, when Ts was lower than 23 ℃, when reaching after Ts+1 ℃, intensification and dehumidification operation were performed, as shown in Figure 7.
When Ts is between 23 ℃ and 27 ℃ the time, when Ts is reached, detect beginning, more than Ts+1 ℃ locate to start dehumidification operation and survey and dehumidifying repeating.
In addition, when Ts is higher than 27 ℃, when Ts is reached, detect beginning, more than Ts+1 ℃ locate dehumidification operation and be implemented repeating and survey and dehumidifying.
After Ts is reached, heat up and dehumidification operation during, room temperature is surveyed to be left in the basket and is heated up and dehumidify repeating same intensification and dehumidifying circulation, withdraw from, unique possible way is from external key input operation stop signal.
Can be obvious by preamble, have an advantage according to the dehumidifying control appliance and the control thereof of aforesaid air-conditioning of the present invention, promptly when room temperature is lowered,, carry out intensification/dehumidification operation by being transformed into warming temperature; When room temperature reaches predetermined temperature, air-conditioning switches to the cooling operation to heat up/dehumidification operation, like this according to the variation of room temperature, heats up and lowers the temperature to operate alternately and switch, preventing that room temperature from reducing, and improve dehumidification rate according to the rising temperature of indoor heat converter.
